[Bug 🐞]: Repeated Exception Handling Error/Sci Lab broken

Opened this issue 2 years ago · 2 comments

Brief description of your issue (aka the problem)

I'm getting the following error over and over in my KSP log (usual size 3MB, with this error chain, 86MB). It also seems to be breaking the Science Lab, (MPL-LG-2) as it will not completely transmit science with ODFC installed (appears to transmit, but science is still in lab, none added at KSC).

Notes:
Lab is the only part on the base with ODFC.
There is a fuel source on the base (LFO).
Other science (sensors, etc) transmits normally.
Uninstalling ODFC causes the Science Lab to Transmit normally.

Steps to reproduce the behavior or issue

Have ODFC installed, have a Science Lab as a part of a Mun base, with data, scientist, antennas, power, etc.
Click Transmit Science.

Expected behavior

Science to transmit, be removed from lab and added at KSC for use.

Actual behavior

Science appears to transmit, but is not removed from lab and is not added at KSC for use.

👍 Thank you @help137

❓❔

Have you reviewed the open issues logs and recent changelogs?

In order to help us help you, please provide:

<KSP_ROOT>/KSP.LOG
and one of the following:
- if Module Manger is installed

Answer 2 · 2023-07-02T07:05:45.000Z

Because ODFC shifted the module indices of Squad's default lab module.

Long explanation: https://forum.kerbalspaceprogram.com/topic/182402-science-lab-not-transmitting/
Other KSP mods with same problem and fix:
sswelm/KSP-Interstellar-Extended#667
sswelm/KSP-Interstellar-Extended@2755fdd

Relavant parts of my ModuleManager.ConfigCache:

UrlConfig
{
	parentUrl = Squad/Parts/Science/LargeCrewedLab/largeCrewedLab.cfg
...
		MODULE
		{
			name = ODFC
...
		}
		MODULE
		{
			name = ModuleScienceContainer
...
		}
		MODULE
		{
			name = ModuleScienceLab
			containerModuleIndex = 0
...
		}
...
		MODULE
		{
			name = WBIModuleScienceExperiment
...
		}

In original file from GameData/Squad/Parts/Science/LargeCrewedLab/largeCrewedLab.cfg, ModuleScienceContainer is the first module. ModuleScienceLab is the second module, which refers to the first with containerModuleIndex 0. Since ODFC inserted itself at the front, everybody's index is shifted and the science lab cannot find the container to transmit the science.

I'm not very well versed with ModuleManager syntax. But the ODFC patch seems to explicitly ask to insert itself as first:
https://github.com/zer0Kerbal/OnDemandFuelCells/blob/master/GameData/OnDemandFuelCells/Config/LargeCrewedLab.cfg#L18

Mods like WildBlueTools just use MODULE without the 0:
https://github.com/Angel-125/WildBlueTools/blob/master/GameData/WildBlueIndustries/000WildBlueTools/ModuleManagerPatches/MM_Stock.cfg#L64
In my ModuleManager.ConfigCache, WildBlueTools modules gets inserted at the end after the Squad modules. Indices remain the same and everything works.

Is there a reason why you have to be the first? I suppose you could try to patch the containerModuleIndex from Squad's lab module. But that sounds pretty fragile if every mod decides to do the same. Probably easiest to just let Squad be first just like how the Intersteller mod fixed this.
